Astronomers have recently discovered a transient exoplanet with the longest year ever seen. Circling its star once every 704 days, Kepler-421b easily wins the title of longest orbit among known exoplanets.
NASA says that finding life beyond Earth is within our reach, even if we cannot physically reach these exoplanets. Still, some experts might disagree that habitable planets are as common as NASA thinks.
Two "goldilocks" planets recently identified by astronomers have been proven to not be as "just right" for life as was initially through. In-fact, they may not even exist at all according to a recent study.
Astronomers now have an innovative new tool that is able to detect methane on alien planets. The organic molecule, widely acknowledged to be a sign of potential life, could be the key to finding organisms beyond Earth.
The number of planets that could support life in this universe may be far smaller than what experts once thought. According to a new study, planets that orbit red-dwarf stars face extreme space weather, making it less likely that life could survive .
Have you ever ordered a dinner for two... for just yourself? Apparently, the growing star Kepler-56 is doing just that. Astronomers have determined that Kepler-56 will be swallowing two of its orbiting planets whole as it becomes a red giant.
Scientists have developed a new way of studying the atmospheres of exoplanets by using Saturn's smog-enshrouded moon, Titan. The new technique shows the significance hazy skies could have on our ability to learn about these alien worlds orbiting distant stars.
Carbon-rich diamond planets may be more common than astronomers previously thought, according to new research.
NASA announced Wednesday that it has found 715 planets outside our solar system. Four of the newly-discovered planets belong to the "habitable zone," meaning that they have the potential to support life.
NASA's planet-hunting Kepler space telescope suffered a failure in one of the reaction wheels that keep it orbiting, the space agency said Wednesday.
With the help of NASA’s Sptizer Space Telescope, researchers are beginning to dissect an exotic class of planets known as hot Jupiters or roasters, due to their tight orbits around their stars.
